星球大战太空雷射攔截概念
1983年雷根在電視演講星球大战
衛星攻擊衛星的概念
海軍實驗室的雷射衛星模型機
星球大戰計劃的出台背景是在冷战后期，由于苏联拥有比美国更强大的核攻击力量，美
国害怕“核平衡”的形势被打破，有需要建立有效的反导弹系统，来保证其战略核力量
的生存能力和可靠的威慑能力，维持其核优势[來源請求]。同时，美国也是想凭借其强
大的经济实力，通过太空武器竞争，把苏联的经济拖垮[來源請求]。
内容
计划由“洲际弹道导弹防御计划”和“反卫星计划”两部分组成。
其预算高达1万亿余美元。拦截系统由天基侦察卫星、天基反导弹卫星组成第一道防线
，用常规弹头或定向武器攻击在发射和穿越大气层阶段的战略导弹；由陆基或舰载激光
武器摧毁穿出大气层的分离弹头；由天基定向武器、电磁动能武器或陆基或舰载激光武
器攻击在再入大气层前阶段飞行的核弹头；用反导导弹、动能武器、粒子束等武器摧毁
重返大气层后的“漏网之鱼”。经过上述4道防线，可以确保对来袭弹道导弹有极高摧
毁率。同时在核战争发生时，以反卫星武器摧毁敌方的军用卫星，打击削弱敌方的监视
、预警、通信、导航能力。

发帖数: 1404 | 17 看来你还真是不太懂。所谓GPS使用低端processor是你自己的想象。严格地讲，绝大多
数情况GPS用低端不是因为囤货太多，而是因为做gps用不着那么强大的性能。用什么主
要是出于成本和设计，不是因为库存。
消费者被厂家忽悠也是你一厢情愿的想法。不论3.5和4.3也好，消费者买gps的时候在
商店里可以随便比较。哪个清楚，哪个好用，一眼看上去就明白了,这又不是什么高科
技。没有哪个傻子看到好用的不去买反而选择难用的。另外，别上来就什么消费者被忽
悠，你不是消费者啊？那么多消费者就你聪明？没听说过最大的愚蠢就是自以为比别人
聪明么？
那两个问题其实是考你玩的。
1.你先搞清楚什么是pda什么是pna再来说话。破解的pna，因为操作系统的限制，只能
实现很有限一点pda功能。
2.你这个回答就是彻底胡扯了。netbook上的sd卡是数据读口，根本不能用sdio卡的gps
。这些都不知道还查？你开什么玩笑啊。
你摆了半天你玩gps的资历，谈什么dell,hp的pda，能刷个rom就显得跟个大拿似的，说
到底和改软件有个毛区别。你见过handspring上的gps么？

还是依据注册的先后一个一个的调？我猜想是后者。所以我还是认为应该卸载原来的那

你可以先把不需要的模块 disable。 改 config。
还有就是好好理解确定你目前慢的时间是在什么模块上，
在干什么事。
SD controller 如果事 SOC 自己带的，用 SDIO 模式一般会比 SPI
快。这个要看 controller 提供什么样的外设借口。一般来说，你
不需要用 GPIO 来做 SPI 就会快很多。 |
